Sepracor hired four former Novartis and GlaxoSmithKline marketing and sales executives as it firmed up its senior commercial management staff.

The Massachusetts company, whose biggest product is the sleep drug Lunesta, appointed Mark Iwicki EVP and chief commercial officer, a new position. Iwicki joined from Novartis, where he led the cardiovascular business franchise.

Also from Novartis, Sepracor brought in Jay Smith as SVP of sales. At Novartis Smith served as national VP of sales and head of cardiovascular innovations marketing.

The two former GSK executives included Dean Giovanniello, whom Sepracor hired as VP of marketing, and Thomas Hoover, named VP of new products planning. Giovanniello was most recently executive director of marketing for GSK’s migraine products, while Hoover served as its therapy area head, business and commercial analysis.

Sepracor said the new hires were part of an effort “to deliver enhanced performance and productivity across our commercial organization.”
